AFFARATUS FOR TREATING REFUSE FROM OIL-REFI'NERIES.

SPECIFICATION forming part of Letters Patent No. 305,097, dated September 16, 1884 Applicniioniled April 11, 184. (No model.) f

.To all whom, it may co/wc'lt:

Be it known that I, HENRY MoMANLs, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of N ew York, have invented certain new and useful Improvements in Apparatus for rlreating Refuse from Oil-Reineries, of which the following is a specification.

The object of my invention is to utilize the waste product from coal-oil and petroleum refineries known as sludge, and which is yordinarily discharged into streams, watercourses, or the ocean. The heavy matter of the sludge sinks and settles upon the bottom, effectu ally exterminating the oysters and other shell-fish, and destroying the ish-spawn. The lighter matter contains more or less spent oil, in combination with sulphuric acid, which oats and throws oiif noisome vapors of an extremely offensive odor, and is a nuisance not only to the people Aon the neighboring shores but to the shipping as well, and is es-` pecially annoying 'to yachts and other low-ly-V ing vessels. I have succeeded in producinga heavy hydrocarbon oil suit-able for lubricating and other purposes, by subjecting the sludge to heat in an apparatus constructed to permit a free circulation, and thorough and uniform heating of the material, however thick and viscid it may be, and regardless of the extent to which it may foam.

Figure l of the drawings shows one form of apparatus embodying my invention, and Fig. 2 shows the same somewhat modified.

The apparatus consists of a hollow vessel or tank, B, which is heated either by an eX- 'ternal furnace, G, below the same, as shown,

or by interior steam-coils, or otherwise. a second vessel, E, and circulatingpipes C G, the former extending from the top of the vessel B to near the top of the vessel E, and the latter from the bottom of the vessel E to near the bottom of the vessel B. On the vessel E are one or more domes, F F, from which pipes a lead to condensing-worms, and the vessel B is sometimes provided with a similar dome and pipe leading tol-a worm. "Valves b are arranged at proper points to control circulation and cut out any of the worms, as may be desired.

lThe sludge is placed in the apparatus to the height of the line x, and the heat is applied to the vessel B, when there will be a circulation upward through thepipe C, and downward through the pipe C', and along bot-h vessels. I

It will be seen that the passages are of coinparatively great diameter as regards the size of the vessels, `so that the circulation is not impeded, and so that as soon as the material begins to foam it can rise freely and pass over to the upper vessel, where there is ample opportunity for the foam to break and settle. By continued circulation the entire mass is gradually brought to a uniform heat, and the contained volatile portions are vaporized and sep arated, the gases passing through the pipes a to the worms, and being then condensed in the form ot' a thick hydrocarbon oil, which may be utilized like other heavy hydrocarbons.

The vessel E may be in the form of a tube or pipe connecting the pipes C C', as shown in Fig. 2.

By constructing the apparatus with circulating-pipes to compel circulation, and providing it with alarge upper receptacle or tank, the gradual heating and eective separation of the gases are secured, however thick and .adhesive the material may be, while the foaming presents no obstacle to the circulation or separation of the volatile portions.

The vessels and circulating-pipes may be of any desired form, arrangement, and dimensions, provided they are arranged to secure the circulation and permit foaming without obstructing the passages.

I claiml y The combination, with a lower vessel haw ing a heating apparatus connected thereto, of an upper vessel, a pipe leading from the upper part of the lower to the upper part of the upper vessel, a pipe leading from the lower part of the upper to the lower ,part of the lower vessel, and pipes leading from both vessels to the condensers, substantially as described. Y

In testimony whereof I have signed my name to this specication in the-presence of two sub` scribin g witnesses.
